This paper presents a local feature descriptor based on Local Binary Patterns (LBP). This descriptor uses binary bit string to represent the local region of images and the integral image to mean filter that makes descriptor building faster. Compared to Scale-invariant feature transform (SIFT)that the calculation is large and the process is time consuming in the description of the characteristics,...
The results of a laboratory study on the electrical performance of 1000kV and 500kV post insulators as well as 500kV bushing covered with wet-grown ice were presented in this paper. The tests were performed in a large-scale artificial climate chamber at UHVAC test base of State Grid Corporation of China (SGCC). The ice formed artificially by super cooled water droplets accreted on the energized insulators...
Pseudo-random code attains more and more people's attention and was widely used in modern engineering. M sequence, as a pseudo-random code of the longest cycle of one of the basic sequence, has always been more research. Therefore, how to design the hardware circuit to generate m sequence is particularly important. In this paper, the nature and generated condition of m sequence were first studied,...
In wireless sensor networks, the localization space can be divided into distinct regions that can each be uniquely identified by sequences in traditional sequence-based localization (SBL). The sequences represent the ranking of distances from the reference nodes to that region. But the average estimate error for locations in a face region is quite in evidence. For the problem of location error, a...
